Which statements best describe the difference between active transport and passive transport?
Understand the Problem
The question is asking for descriptions that differentiate active transport from passive transport, focusing on their characteristics and energy requirements.
Answer
B: Active transport requires ATP. Passive transport does not require ATP.
The final answer is B: Active transport requires ATP. Passive transport does not require ATP.
Answer for screen readers
The final answer is B: Active transport requires ATP. Passive transport does not require ATP.
More Information
Active transport differs from passive transport primarily because it requires energy, generally in the form of ATP, to move substances against a concentration gradient. In contrast, passive transport moves substances along the concentration gradient without needing energy input.
Tips
A common mistake is assuming both transports require energy or are passive by nature. Remember, active transport requires energy input, usually ATP.
